Testing Procedures

Phosphorus

-Only a ¼ teaspoon of the clear solution is required for this test, and it is diluted with distilled water once placed in the tube. If the solution is not diluted the blue color development would be too dark to read.

-The capped tube should be mixed until the tablet disintegrates. Invert the tube repeatedly allowing the air bubble to travel from one end of the tube to another. Do not shake vigorously.

-Some tiny particles of the tablet may be visible once the tablet disintegrates. These particles will not totally dissolve and will not affect the test results.
